SILENCERS
Ventilation system too loud? We can help you! The flexible ventilation silencers, also known as telephone silencers, significantly reduce the noise level caused by your ventilation system. The silencer is installed in the duct run and ensures that you can sleep peacefully again at night.
Intelmann® Insert Silencer Ø 80–200 mm – Sound Insulation & Airflow Element for Round Ventilation DuctsThe Intelmann® Insert Silencer is the compact and efficient solution for reducing noise while simultaneously controlling airflow in ventilation systems. This innovative 2-in-1 element is inserted directly into round ventilation ducts and combines sound insulation and airflow regulation in a single component.Available in sizes Ø 80 / 100 / 125 / 160 / 200 mm, the insert silencer is suitable for a wide range of applications in both residential and commercial settings.The special design enables effective absorption of flow and fan noise, while allowing the airflow to be individually adjusted. The fine adjustment is made by removing pre-punched elements, enabling precise regulation of the airflow volume.Advantages at a glance:✅ 2-in-1 solution – Sound insulation and airflow control✅ Effective noise reduction – Minimises flow and fan noise✅ Individually adjustable – Air volume adjustment via punched-out sections✅ Modularly expandable – Multiple elements can be combined for higher insulation performance✅ Space-saving – No separate silencer housing required✅ Easy installation – Direct insertion into the ventilation ductTechnical details:✔ Product name: Intelmann® Insert Silencer✔ Diameter: Ø 80 / 100 / 125 / 160 / 200 mm✔ Installation: Directly in round ventilation duct (insert)✔ Function: Sound insulation + airflow control✔ Material: Sound-insulating special foam✔ Fire protection: Fire class B✔ Emission class: M1 (very low emissions)Material & Safety:The used fire-optimised foam is mould-resistant, low-emission and safe for health. In the event of fire, no harmful smoke or toxic substances are released, making it suitable for use in sensitive areas.Installation & Function:– Insert the silencer into the ventilation duct– Then install the plate valve or exhaust element– Adjust airflow by removing the pre-punched openingsApplication & Areas of Use:The insert silencer is ideal for:– Central residential ventilation– Exhaust systems in bathrooms and kitchens– Supply and exhaust air ducts– Noise reduction in living, sleeping and working roomsWith the Intelmann® Insert Silencer, you get an efficient, space-saving and flexibly adjustable solution for quiet and optimally balanced ventilation systems.
